In Direct mode you can switch video with the press of a single button.

In Preset mode, you can confirm the input video with the preview monitor before
switching the video.

■ Video Signals Handled by the V-44SW
HD
An abbreviation for “High Definition,” HD is a generic term for television formats that, in comparison to
conventional TV formats, provide higher resolution and an improved angle of view, and deliver a
heightened sense of presence by means of large-screen. This is also referred to as HDTV.
Although there are a number of different types of HD, which can vary depending on the country where
the technology was developed, the V-440HD utilizes the standards recommended in BT.709-3,
established by the ITU in February, 1998.
RGB
This format, used for output of video images with computers and other digital devices, uses video signals
whereby each of three main colors, red (R), green (G), and blue (B), are handled separately.
SD
An abbreviation for Standard Definition, this refers to formats currently in general use (such as 480I), as
opposed to HD (High Definition).
